Masonry Contractor in Fontana, CA - Repairs That Leave Good Work Standing
Fieldstone Ontario Concrete and Masonry is a masonry contractor based in Ontario that repairs block walls, brick, chimneys and foundations for Fontana homeowners, and builds new walls, walkways and paver driveways that suit the house.

Masonry work on Fontana homes
Fontana is one of the cities around Ontario where we fix block walls, brick and chimneys, the same work we do in Rancho Cucamonga, Jurupa Valley and out in West Covina. Before I started this business in 2023, I spent years patching walls, steps and block fences at rentals all over this area.
On Fontana jobs we mostly see stucco houses with block fences along the side and back yards, concrete driveways and walkways, and brick chimneys, planters and steps on the older homes. Those fences take a beating from sprinklers, tree roots and the occasional car. That's why the first thing I do is find out why a wall moved, because patching over the cause just means it cracks again. Once I know the cause, I can tell you whether the fix is one section or the whole run, and that shapes the rest of the job.
What we do for Fontana homes
Cracks in a block foundation under a Fontana house can be minor or a sign of settling, and I'll tell you which before we repair anything.
Loose brick or cracked mortar at the top of an older chimney lets water in. We rebuild just what's failing so the rest keeps doing its job.
Is the mortar between your bricks sandy or missing? Tuckpointing scrapes out the worn joints and refills them, matched in color so it blends with the old work.
Cracked or flaking bricks on a planter, step or garden wall rarely mean the whole thing has to go. We replace the bad ones and keep the rest.
Swapping a cracked concrete driveway for pavers? We dig out, pack a solid base and lay pavers that can be lifted and reset if one ever settles.
On sloped yards where soil pushes against a fence or patio, we build retaining walls with drainage behind them, since trapped water is what tips most walls over.
Older brick and block around Fontana homes can often be brought back with cleaning, repointing and a few replaced bricks, which costs far less than rebuilding.
Adding a fireplace to a family room or patio starts with where it'll sit and how it vents, so I walk through both with you before we build.
Stone veneer, a thin stone facing set over an existing wall, dresses up a stucco front, column or fireplace without the weight of full stone.
Block fences line many Fontana back yards, and we build new ones or fix leaning and cracked runs, often just one section instead of the whole fence.
For an addition, garage or raised floor, we lay the block foundation walls on a proper footing, because everything above depends on them being straight and solid.
Planning a grill island for the back yard? We build the block base and finish it in brick, stone or stucco to match your house.
A walkway from the driveway to the front door or side gate gets used every day, so we set it on a packed base that keeps it flat.
A brick garden wall, planter or entry wall suits a lot of older Fontana homes, and we pick brick and mortar color to sit right with the house.
Natural stone steps, walls and borders take more fitting by hand than brick or block, and that slower work is what makes them last.
If only a few joints have cracked, pointing fills them with fresh mortar without cutting out every joint, and I'll tell you when that's all you need.
What Fontana block walls and brick need
I come out to every Fontana job myself and stay on site with our crew, so the person who looked at your wall is the one making sure it's fixed right.
Told what can wait
If a crack is cosmetic and isn't getting worse, I'll tell you it can wait instead of selling you a repair.
Sound brick stays put
If your mortar or brick is still doing its job, I'll say so, because tearing out good work just costs you money.
A tidy site, every day
Working around tenants taught me to keep paths clear and clean up as we go, since your family still lives there.
Licensed, insured and guaranteed
We're licensed and insured, and every job we do is backed by our satisfaction guarantee.
New work that fits
New block, brick or stone gets matched to your home's color and style, so it looks like it belongs there.
Fontana masonry questions we hear
Who takes building permit applications in Fontana, the city or the county?
If your house is inside Fontana's city limits, the city's Building & Safety department takes the permit application, but the unincorporated parts of Fontana are regulated by the county instead. That's why the city asks contractors pulling permits to call its Planning desk and check the job site first. When your job needs city sign-off, we take care of the permit and set up the inspections.
How much does masonry work cost in Fontana?
Your price comes down to how much of the wall, brick or chimney actually needs work, how big it is, which materials you choose and how easy the spot is to reach. The schedule mostly turns on whether the city has to sign off, how long materials take to come in and when you'd like to start. I write up what I'd do and why after I've seen it, so you're looking at a number for your job, not a guess.
How do I build a block wall on the property line in Fontana?
When a fence or wall goes directly on the property line, the city's permit process requires a Neighbor Authorization, which is your neighbor's written okay. It's worth a friendly talk over the fence before we start. For any wall near the line, I check with the city early so nothing stalls once the job is planned.
Who can sign for a building permit in Fontana?
Once the permit fees are paid, only the contractor signing on record or the property owner can sign for the permit, and anyone else needs written permission notarized by one of them. The city's permits page also says an owner who pulls a permit for a contractor's work takes on the liability for the project, including taxes and personal injury, so it usually makes sense for us to sign as the contractor. If you just bought the house, you'll need proof of ownership too.
How long is a Fontana business license good for, and does an out-of-town contractor need one?
A Fontana city business license lasts one year from the date it's issued, and the city requires one from every business working inside city limits, even businesses based somewhere else. It costs $35 to apply and $15 to renew each year, plus a yearly business tax based on estimated gross receipts. That rule covers contractors from out of town, us in Ontario included, so it's a fair question to ask anyone you're thinking of hiring.
Can I apply for a building permit online in Fontana?
Building & Safety points applicants to its Build Fontana Public Portal and takes permit payments online. Each online payment carries a service fee, a percentage plus $0.20 on a card or a flat $3.00 if you pay by ACH bank transfer. You can also apply at the counter at 8353 Sierra Avenue, which is open Monday to Thursday and closed Fridays, and if we're pulling your permit, we handle all of it.
